AI Technical Summary

Benefits of technology

[0020]For certain applications, e.g. such as liquid / liquid separators or heat exchangers, the enclosure may further comprise a gas exhaust orifice centered on the longitudinal axis of the enclosure and situated at the longitudinal end of the enclosure where the outlet orifices are positioned. This exhaust orifice enables as much gas as possible to be extracted upstream from the fluid outlet orifices so as to minimize the gas content of the fluid delivered through them.
[0022]Preferably, the fluid guide means are configured to enable the fluid to make two turns around the longitudinal axis of the enclosure on going from the inlet orifice to the outlet orifices. This characteristic makes it possible to obtain an enclosure that is very compact by reducing the distance travelled between the inlet orifice and the outlet orifices.

Problems solved by technology

Depending on the intended application, such manifolds may present certain limits.
Such manifolds having a height of several meters makes them bulky, which can be problematic for the configuration of the undersea installation, particularly when the installations downstream from the manifold are low down.
Furthermore, as a result of their function of sharing the incoming stream as a whole, such manifolds do not serve to separate gas from liquid.

Embodiment Construction

[0031]The invention relates to a multiphase fluid manifold for fitting to undersea effluent-treatment equipment, in particular to segmented gravity separators, which are used in hydrocarbon production at great depths offshore.

[0032]The term “multiphase fluid” is used herein to mean a fluid comprising at least two different phases, e.g. a liquid phase and a gas phase.

[0033]FIGS. 1 to 5 show a manifold 2 in a first embodiment of the invention.

[0034]The manifold 2 comprises in particular a cylindrical enclosure 4 having a longitudinal axis X-X that is positioned vertically. At its bottom longitudinal end, the enclosure 4 has an inlet orifice 6 for the multiphase fluid. At its top longitudinal end, opposite from the bottom end, the enclosure presents a plurality of cylindrical outlet orifices 8.

[0035]More precisely, the inlet orifice 6 leads into the enclosure 4 along a direction that firstly is substantially tangential to the enclosure, and that secondly forms an angle α with a transve...

Abstract

A multiphase fluid manifold comprises a cylindrical enclosure having, at one longitudinal end, an inlet orifice and, at an opposite longitudinal end, a plurality of cylindrical outlet orifices of the same right section that are regularly distributed around a longitudinal axis of the enclosure and that are aligned in a common plane extending transversely to the enclosure, each of the inlet and outlet orifices leading to or from the inside of the enclosure along a direction that is substantially tangential to the enclosure.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to the general field of manifolds for multiphase fluids serving to take a flow of fluid made up of a plurality of different phases, and to subdivide the flow in equal portions into a plurality of fluid flows, each having the same flow rate and the same composition.[0002]A particular field of application of the invention relates to undersea effluent-treatment equipment for use in producing hydrocarbons, e.g. oil and gas, coming from undersea production wells.[0003]Subjecting hydrocarbons coming from undersea production wells to treatment undersea is becoming a real need for optimizing production, in particular at great depths. Among various means used for undersea treatment of hydrocarbons, it is known to have recourse to undersea gravity separators of the gas / liquid type, referred to as “multi-pipe separators” or as “condensate traps”, that serve both to optimize production from wells, and also to manage stopping and res...
